Than you for the fast response.
Next week if you make some Avast beta build with fix for Win8/8.1 x86 I'm willing to test it, no problem, iirc my parents on their PC they're still using Win8.1 Pro 32bit + Avast Free and afaik they didn't turned on that PC for almost 2 months so they're probably still on Avast Free Antivirus 22.3.6008 (build 22.3.7108), not completely sure but that's probably the case. So, on their PC I can do either a upgrade from current Avast Free Antivirus 22.3.6008 (build 22.3.7108) to Avast Free Antivirus 22.5.6015 (build 22.5.7263) + µUpdate or to wipe completely current Avast Free Antivirus 22.3.6008 (build 22.3.7108) with Avast Clear 22.5.7263 and replace it with latest beta-test build if you provide download link, whatever helps community to get the fastest solution.
Cheers!
